Natural Resveratrol 5–99% Polygonum Cuspidatum Extract

Pure Natural Resveratrol 99% Powder

Natural Resveratrol (5–99%) is a high-purity botanical extract sourced exclusively from Polygonum cuspidatum (Japanese Knotweed). Offered as a brown-to-white fine powder, it contains the active polyphenol resveratrol, known for its strong antioxidant capacity and wide applications in anti-aging, wellness, and beauty formulations.

Produced under GMP, ISO22000, HACCP, HALAL, and KOSHER certified systems, our resveratrol meets strict EU standards for PAHs, pesticides, plasticizers, and ETO. We guarantee 100% natural plant origin with no added excipients (no dextrin).

Carbon-14 and Carbon-13 isotope analysis reports verify authenticity and clearly distinguish it from synthetic and fermentation-derived resveratrol. With excellent stability and high bioactive purity, it is suitable for nutraceuticals, cosmetics, functional foods, and pharmaceutical R&D.

OEM customization for purity, packaging, and technical documentation is available for global manufacturers and wholesalers.
